The hinge pin 11 is preferably provided at its respective ends withsemicircular bearing collars 22, 22, which are interposed between'saidhinge pin and the opposing surface of the box 12, said bearing collarsserving to form a uniform bearing surface for said hinge pin, whereby itis free to turn in its bearings with a minimum resistance,

It will be understood that thebox 12 is formed of flexible sheet metaladapted to be struck up with dies and when so formed it is provided withasemi-cylindrical member 19,

shown in Figs. 1, 5 and 6, for the reception of the ends of the hingepin 141.K The spring 18 is provided with a longitudinal slot 20. Theslot 20 is adapted to'be placed over and around the vertical lockingplate Swhen the lug 21 is inserted through the slot 20 and turned backagainst the under side of said spring, as shown in Figs. 1 and 4,whereby said sprlng 18 is securely retained in place.

'It will, of course, be understood that the over-lapping frame member 4is secured to the under-lapping frame member 1 by bringing the hingeplate 9 to the horizontal position shown in Fig. 1, whereby the verticallocking member 8 is caused to engage the bracket 2 of the under-lappingframe member. It will also be understood that the bag is unlocked by areverse movement of said hinge plate 9.

Having thus described my invention what vI claim as new and desire tosecure by Letters Patent is- 1. In a baglock of the describedolasscomprising a hinge plate, a vertical locking member aiiixed to saidplate and a support ing box aixed to. the over-lapping frame member ofthe bag ;-a hinge pin secured to said hinge plate and having itsrespective ends terminating within the vertical walls of said supportingbox, a vertical locking member secured to said hinge plate, a springplate adapted to hold said hingeplate in its bearings in said supportingbox, means for securing said spring plate to said supporting box againstthe retaining bearings of said hinge plate and means for securing saidsupporting box to the over-lapping frame member oi. the bag.

2. A bag lock ot the described ela-ss comlapping member of a bag frame,a spring retaining lug formed integral with said box, a plate hinged tosaid supporting box, a locking member affixed to said hinge plate, aspring plate provided with a longitudinal slot for the recept-ion ofsaidlocking member, a retaining lug, said lug being` inserted throughsaid slot and'turned back against the under side of said spring plate,said lug being adapted to retain said spring plate in yielding Contactwith the retaining lugs of said hinged plate. 1

3. In a bag lock of the described class comprising a hinge plate, avertical locking member aliXed to said plate and a supporting boxaiiixed to the over-lapping frame cular bearing plate located beneaththe respective ends of said hinge pin, a hinge plate secured to said pinand a locking `member secured to said hinge plate, a spring platesecured to said supporting box and adapted to bear against one end ofsaid hinge plate, means for securing said spring plate in contact withsaid box andmeans for securing said box to the over-lapping frame memberof the bag.
